Legendary Actions
Details
Made of fiery smoke coalescing into a vaguely humanoid shape, a firegeist is little more than wisps of black smoke and spots of brighter flame.
Elemental Echoes. When a fire elemental meets its destruction in a particularly humiliating fashion while summoned away from its home plane, what returns is a firegeist. Malevolent and resentful, less than their former prideful selves, they exist for revenge.
Indiscriminate Arsonists. Firegeists are not adept at telling one humanoid from another, and so burning any similar creature will do, providing it is flammable.
Brighter Light, Darker Smoke. A firegeist can shine brightly or be primarily smoky and dark, as it wishes. It always sheds a little light, like a hooded lantern.
